Author prepared to admit claim to be of high standard? (7,7)

I believe the answer is:

william golding

'author' is the definition.
(British novelist)

'prepared to admit claim to be of high standard?' is the wordplay.
I cannot quite understand how this works, but
'be' could be 'go' (going is a kind of being) and 'go' is located in the answer.
This may be the basis of clue (or it may be nonsense).

(Another definition for william golding that I've seen is " British author".)

I've seen this clue in The Times.
